I was incorrect. The problem is E85 has no problem burning down into the tank, where a large pressure increase could make the tank rupture and a large fire break out. Petrol kills the fire if the ratio fule:air becomes too rich, E85 does not.
I was taught the problem with lockable handles became apparent in the 00’s when E85 became a thing, as it ignites much more easily from static discharge than gasoline or diesel. Maybe I was taught incorrectly, maybe you guys had E85 earlier than us (Sweden).
So, not a language win after all?
Heat up in the drivers’ seat, or just grab a pack of gum from the glove compartment. Enough to charge up statically and become a fire hazard.
